i've got exactly this kinda setup.
i got a slotload DVD/CDRW drive and IDE adapter from
Mini ITX.com storeand a 4way IDE adapter from
Power Computingyou can then use either a 2.5" or 3.5" IDE harddrive and a normal 3.5" drive cable to hook up your CD drive, and maybe a couple of other devices too.
my aim is to keep everything in the normal A1200 case. :-) i had to use the power flyer as none of the other 4way IDE adapters would have given me enough clearence in the case.
